Annotation: The article proposes a measurement procedure to calibrate the measure of the power quality parameters for determining the correction of the reproducible negative sequence ratio. The measurement procedure based on the method of indirect measurement of the negative sequence ratio using the precision voltmeter of the alternating voltage. The contribution of the input quantities is analyzed, the analytical expressions for calculating the sensitivity coefficients are obtained and the measurement uncertainty budget is proposed. The measurement results obtained from the calibration of the multifunctional calibrator by using proposed measurement procedure are presented and the expanded uncertainty is estimated.

Keywords: negative sequence ratio; alternating voltage; precise voltmeter; uncertainty of measurement
